Usage of our OpenSource firmware on a closed proprietary software
So, an user warned me about this, that Marcoq is making his work as a closed proprietary while is uses our own firmware, licensed as GPL. GPL license is probably is the most well known license in the world and does not permit someone to close it and that is why I choose that license when I started the project.
Can someone with more knowledge on this subject give his opinion if Marcoq is acting correctly accordingly the GPL license??
If the derived source is available this is OK. Is it? Also the usage of the term proprietary seems wrong. It isn't, it is GPL3 open source.
Selling it is OK - as long as the derived source is provided and the GPL licensing terms are not removed.
From https://www.techrepublic.com/blog/linux ... -software/
The GNU project itself "encourages people who redistribute free software to charge as much as they wish or can... You can charge nothing, a penny, a dollar, or a billion dollars. It's up to you, and the marketplace."
Please note that "as much as you wish" only applies to the executable form of the software, not its source code. This is explained in subsections 6a and 6b of the GPL: if you want to sell a binary copy of a GPL software program, you must include either its complete source code or a written, formal offer valid at least three years to provide it to whoever possesses the binary. In more detail, you have to provide:
a copy of the complete sources for a price no more than your reasonable cost of physically delivering them, or
"access to copy [the complete sources] from a network server at no charge"
